● Product Introduction:
Multi-layer FR-4 PCB have multi-layer copper layers，two of which are on the outer surface and the remaining layers are integrated into inner of the board, there have a dielectric layer between each two layers, so that the copper layers can be independent of each other without short circuit，the circuit trace in each copper layer are connected by vias.The more inner layers, the larger the layout space.
